Section 1667 (66RFE Automatic Transmission - (Service Information) - 2500 Hd): Disassembly

WARNING: This page is about a different car, the 2017 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:

Tag all snap rings, thrust washers, washers, shims, spacers and thrust bearings, etc. during disassembly for quick identification and assembly. Failure to follow these instructions will cause damage and transmission failure.

  8. Using (special tool #8266-17, Spline Tool, RFE Output) from (special tool #8266B, End Play Socket Set) (1) and (special tool #C-3339A, Set, Dial Indicator) (2), measure and record the input shaft end-play.
    NOTE:

    When measuring the input shaft end-play, two "stops" will be felt. When the input shaft is pushed inward and the dial indicator zeroed, the first "stop" felt when the input shaft is pulled outward is the movement of the input shaft in the input clutch housing hub. This value should not be included in the end-play measured value and therefore must be recorded and subtracted from the dial indicator reading.

    NOTE:

    (special tool #8266-17, Spline Tool, RFE Output) will fit loosely onto the input shaft, this should not effect the performance of the adapter.
